mobilenvidia Posted February 10, 2008 Report Share Posted February 10, 2008 After 18months of faithful service my Dell i9400/E1705 has died. I'm fairly sure it's the video card, it looks to have overheated, as when I pulled it out of the laptop it was still quite warm. The vents had build up with dust (CPU and Video) and no doubt caused the heat build up. Had been keeping an eye on the temps (low 60's) up until last week when I reinstalled Vista but not nTune. I was happily typing up a new post here on the new Core 2 Duo Peryn (45nm) CPU's that are coming out (some are already out) The mouse stopped moving followed by a few secs later the screen going blank (backlight still worked) Rebooting machine took a few goes but went back to desktop in Vista but only lasted a few seconds and mouse freeze then screen went blank. Reboot again but this time screen had some odd looking graphics for a split second then nothing except the back light. Pulled the laptop completely apart gave everything a clean, but nothing, my baby is dead :P Anywho, now I'm in a bind, do I get a new lappy or do I replace the video card ? Does anyone have a spare Dell E1705/M1710/i9400: Go7800(GTX) Ebay $360 Go7900GS Ebay $195 Go7900GTX Ebay $230 Go7950GTX Ebay $450 Quadro FX1500 Ebay $129 Quadro FX2500 Ebay $199 Quadro FX3500 Ebay $399 If yes and you are willing to ship this thing to New Zealand step right up. Quite appy to pay for it and the shipping costs. Reply back here and I'll PM any interested party Other thing is to upgrade my machine now, I was waiting for a Quad Core machine that will no doubt come out in the future. Lots of thinking and juggleing to do. In the mean time here I am on my Wifes Dell D820 (at least it's got a nV based GPU) Any help here appreciated. [uPDATE] Not much else to do but try out various things: Video card in, machine boots then after a few minutes crashes and resets. The heat pipe gets really hot after a few minutes (mind you with it @60+ idle before problem, it will be hot to the touch) The video fan comes on so this still works. With no video card the machine just turns the power light on and nothing else. I'll see if I can take the lappy in all it's pieces to work tomorrow and attach it to a external monitor, to rule out the Inverter. [uPDATE II] Just got the heatsink of the Video card and noticed the bottom heat-plate that sits over the 4xRAM chips was discoloured where the RAM chips heat pads are. So I can safely assume the RAM is causing my grief. Upon closer inspection 2 of the other 4 RAM chips (4 chips per side) were grey in colour not the bright black the other chips are. I cleaned off the AS5 I put on a year ago, this was in better condidition than the CPU. Replaced the AS5 then put the heartsink back together again. Pulling the heatsink apart requires special tools a tiny star shaped screw driver or alan-key is needed (I had neither but improvised) Without the proper tools dont' contemplate doing this your self. I plugged my work LCD display in (DB15), and powered up. The BIOS splash screen popped up :) But there was pixelation on this screen the Vista boot screen (where it askes to boot normally or Safemode bla bla) was fine. Didn't have a key board so couldnt' test further. This gave me hope of having a semi workin machine, I take the machine back home plug the LCD back and nothing :P Machine boots, but no picture :rofl: Will zip around to a mates place and grab a CRT and see if I can lower the Memory/core speeds to as low as they will go. Then possibly I can use it till replacement turns up. [update III] A very kind soul has taken pity on me and I'm awaiting a go7900GS from Dallas TX Thanks for those who offered me their cards, it's very much appreciated. Will be good to get my machine working again. I just hope there is nothing else wrong (crosses fingers) [update IV] I'm back, well sort of :) The Laptop is back in action, but still in pieces. The LCD works again, and no funny pixelation on the screen. Really weird, for hours the LCD refused to turn on. Went back to work grabbed my old CRT monitor, and this worked but with pixelation on the BIOS splash screen. Just as a thought I plugged the LCD in and now both displays work. Unplugged the CRT and LCD continues to work. Quickly installed nTune and watch the temp rocket up to 70degC, machine crashed and after restart I quickly zipped over to the overclock page and lowered the core/mem to 92/126Mhz (lowest) Temp went down to 46 but while typing this has shot back up to 56 now cruising back down again. I'm using 156.69 which Vista found as a driver update online, powermizer doesn't work but overclocking does. Strange happenings, hopefully this will last me till the replacement arrives. Hopefully this may come in useful for someone in the same predicament in the future. [update V] Next morning now. GPU temp climbs to 77degC and then the CPU fan comes on and cools thing down to 65degC and stop, GPU climbs back to 77degC and CPU fan starts again. In the mean time the GPU fan is spinning all the time, now I can can't tell if it's spinning fast or in it's slower mode. I would assume slower mode, with the lack of cooling going on. Also quite odd that the CPU can draw or push air all the way accross the other side of the laptop. The CPU is stopping the GPU from cooking (thankfully). Before going to bed last night the GPU was stuck on 60degC and didn't budge, wonder if going to stanby has anything to do with it. This has me really baffled. Is there an app that control fan switching for the i9400, Fangui in it's various forms doens't work in Vista x64, this was a really useful app before I went x64. This has become quite a book now.
